Marking device and inker therefor



Patented Oct. 9, 1951 UNITED' STATES PATENT OFFICE 2,571,038 MARKING DEVICE AND INKER THEREFOR Merrill E. Boekeloo, San Gabriel, Calif. Application September 12, 1946, Serial No. 696,525 1 Claim. (01. lei-403i My invention relates to marking devices of the general type disclosed in my U. S. Letters Patent No. 2,273,816, dated February 24, 1942, and over which the instant invention is designed as an improvement.

v The primary object of the instant invention is to provide a marking device in the form of a hand stamp which is adapted for quick, easy use with one hand for successive marking operations with inked type and for re-inking between marking operations by light finger pressure.

Another object is to provide in a device of the character and for the purposes set forth, an inking roller which is adequately protected against accumulation of dust and dirt thereon and covered so as to prevent the fingers or the hand, or the work, from coming into contact therewith and becoming smeared with ink.

Still another object is to provide for changing the position of the inking roller so that diiferent surface portions thereof will be used in inking and uniformly coated with ink.

Other and subordinate objects, also comprehended by my invention, together with the precise nature of my improvements, and the advantages thereof will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in side elevation of my im- Figure 3 is a view in vertical section taken.

on the line 3-3 of Figure 2, and

Figure 4 is a similar view taken on the line 44 of Figure 2.

Referring to the drawing by numerals, my improved marking device, or stamp, as shown, comprises a casing I of substantially rectangular form, preferably, and of a suitable size for holding in the palm of the hand, said casing I including a top 2,- sides 3 with lower front corner notches 4 therein of right angled form, a front plate 5 extending from the top to said notches 4 and secured to the sides 3 by sided flanges 6 on said plate and screws I extending through the flanges 6 and said sides 3, and a lower rear corner bar 8 connecting the sides 3 together. The back and bottom of the casing l are preferably open. A rear edge flange 9 on the top 2 extends across the upper portion of the'back of the casing I to partially close said back.

A yoke II) of inverted U-shape depends from the top 2 of the casing I adjacent the rear of said casing, with the bight II thereof detachably secured by a screw I2 to said top 2, and the sides I3 thereof spaced from the sides 3 of the casing I and provided with bottom edge notches I4 therein. A flat bar I5 is fitted in said notches I4 with ends I6 turned up against the sides I3 of said yoke Ill.

Wheels, as at H, fitted side by side between the sides I3 of the yoke II], in the upper portion thereof, and rotatable on a transverse shaft I8 fixed at its ends in said sides I3, support type bands I9 having raised type '20 thereon, and which are trained over said wheels I! and around the fiat bar I5 over which said bands I9 are slidable under rotation of the wheels I! and which provides a backing for the type 20, located slightly below the bottom of the casing I so that selected type 20 positioned below said bar I5 may be pressed against the work, not shown, without the bottom of the, casing I engaging the work. The bands I9 hold bar I5 in the notches I4. Relatively larger diameter adjusting discs 2| on the sides of the wheels I! provide for finger adjustment of said wheels to feed the bands I9 and the selected type 2|] into printing position beneath the bar I5. A transverse shaft 22 is suitably fixed in the sides I3 of the yoke I I), between the wheels I! and the bar I5, with its ends seating upwardly in vertical slots 23in the sides 3 of the casing. The shaft 22 stabilizes the yoke I0, and hence the parts carried thereby, against play in the casing I and serves other purposes presently clear.

A U-shaped inking bail 24 is provided in the bottom of the casing I with an inking roller 25 thereon on a shaft 26 extending across said bail and journalled in the sides 21 of said bail. The bail 24 has straight sides 2? fitting flat between the sides 3 of the casing I and swingably mounted on the shaft 22 so that said bail is swingable downwardly about said shaft from a normal position in which it extends forwardly of the shaft to a depending inking position in which the inking roller '25 engages the type 26 disposed beneath the bar I5. The sides 21 of the bail 24 are adapted'to engage the bottom edges of the flanges 6 of the front plate 5 to establish the normal, upswung position of said yoke l0, and to engage the cross 'bar 8 to establish the downswung, inking position of said yoke. A spring 28 coiled around the shaft 22, between the yoke Ill and one side 3 of the casing I, and having opposite ends bearing against the shaft 26 and one upturned end I6 of the bar I5, urges said bail 24 into its normal described position. The bail 24 is provided with a front and bottom bridge portion 29 partially housing the inking roller 25 to protect same against accumulation of dust and dirt thereon, and forming a guard preventing the inking roller 25 from contacting the hand of the user of the device, and also from engaging the work when said bail is in normal position. Hand wheels 30 are provided on the ends of the shaft 26, outside the bail 24, for manually rotating the inking roller 25, for a purpose presently seen.

An ink pad 3l'is suitably fixed to the bottom of an inturned bottom edge ledge 32 on the front plate 5, and against which the inking roller 25 is adapted to be yieldingly pressed'by the spring 28, into normal position of the bail 24. As will be noted, in the normal position of the bail2'4, the bridge portion 29 thereof overlaps the front plate and the sides 2'! of said bail overlap the top edges of the notches 4, all to prevent dust from accumulating on the inking pad 3! Also, in the normalposition of. said bail 2 4, thebottomedges of the sides 27 are flushwith thebottom edges of the sides so that said bailifi l is out-of the way when. marking with the device. As will be-seen,. the inking roller 25 may be rotated by thehand wheels 38, against the ink pad- 35. This permits the use of paste ink on the inking pad. 3 l-and smoothing suchink on said roller so as 5010bviate clogging. of. the type 23.

' Finger. operated means is provided. for moving: the. bail E i-into inkingzposition, as follows. A substantially triangular rocker plate 3?; is swing.- ably mounted on a cross, shaft 35 in the upper front corner of the casing; l. alongside one side 3 of said casing, said plate depending from said shaft. and having a lower rear, corner lug 35, thereon above and. in the rear or the cross shaft, 22.. A cord is. connected 6218- end, as a-tPSLto. said lug 35 trained undera pulley. 5.8 on the shaft. 22,. and connected at itsv Other end, as; at,

grasped in the palm of the hand andthetypelll selected for printing are pressed against the work, not shown, by hand pressure on said casing 1. By exerting rearward pressure on the button 43, through a finger of the hand grasping the casing I, the push rod 4!! may be thrust inwardly offlthe casing l to cause the rocker plate 33 to be, swung rearwardly and upwardly. Such swinging of the rocker plate 33 exerts, a pull on the cord 36' whereby the bail 24 may be swung into the. desired inking position, shown in dotted lines in. Figure 3, and in which the inking roller '25 has been caused to wipe over the selected type to ink the same. In the normal position of the bail 24, the inking roller 25 is always maintained against the ink pad 31 so that by rotating said inkin roller 25 through the medium of the hand wheels 35 ink maybe thoroughly'and evenly ap- IChe proper type 2!} are. brought plied to any surface portion of said roller. By disconnecting the cord 36 and removing the screw l2, the yoke i0, together with the parts carried thereby, and the bail 24 with the inking roller 25 therein may be removed downwardly from the casing I as a unit for cleaning or other purposes.

The foregoing will, itis believed, suifice to impart a clear understanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

I claim:

Ina hand stamp, a casing adapted to be held the hand and having an open bottom, marking means at the bottom of said casing for pressure against work to be marked by hand pressure exerted downwardly against the casing, and means for applying; ink to said marking means comprising a transverse inking pad in said; casing, a bail, m,eans pivotally mounting said bail said casing, forswinging upwardly and down wardly into and out of the bottom of said-casing respectively, a roller mounted in said bail for engagement with saidpad by upwardswinging of said bail and for rollingengagement with said' marking means by downward swinging of said bail, spring means for swinging said bailupward- 1y to press said roller against saidinking pad; and means for swinging said bail downwardly in opposition to said spring means; comprisingwa plunger rod slidably extended into said. casing and slidable inwardly thereof by finger pressure,
